  • a condition that the steering torque is equal to or larger than the predetermined value Ts is set. It is desirable to set the third upper limit value Iah2 to a value larger than a current upper limit value equivalent to the predetermined value Ts. Consequently, in a state in which the idle stop control during traveling is performed, for example, before steering is increased and limitation of the assist amount for the steering torque is performed, it is possible to restart the engine and avoid limitation of the assist amount to secure steering performance.
  • the present invention is not limited to the embodiment.
  • the third upper limit value Iah2 is set to a fixed value.
  • the third upper limit value Iah2 may be changed on the basis of the vehicle speed V.
  • the third upper limit value Iah2 only has to be set continuously or stepwise to decrease as the vehicle speed V falls. Consequently, it is possible to further suppress the assist amount for the steering torque and suppress power consumption while securing the assist amount for required steering torque corresponding to the vehicle speed V.
  • the assist current upper limit value Iah when the assist current upper limit value Iah is changed, the assist current upper limit value Iah may be changed stepwise rather than continuously or may be changed at a time.
